Spring brush for timers



1,419,039. Specification of in To all whom it 'may concer/n:

Be itknown that l, An'rrroivv (innere-tg citizen of the United States, residing et New York, in the county of New York en@ Sto-te of New York, have invented a new and neeful Improved Spring Brush for Timers, of which the following is a specification.

This invention genereiiy stated reietes yto timers for internal combustion engines and has more particular reiotion to e brush therefor.

An object of the invention is to provide for an even distribution of spark to the cyiinders of en internal engine whereby the engine may be easily started. A further ob ject is to provide a brush of simpiied eenstruetion, of efficient and inexpensive cher acter and one capable of having; Worn parte readily replaced Withoutnecessitetingpurchase of e new brush. A stili further eb jeet'is to provide o brush which may be applied to a timer casing having e Worn `or pitted bea-ring surface whereby the opere tion of seid brush in time will cerise seni surface to become perfectly smooth. Other end further objects reside in the provision of generati details of construction and in tile arrangement and combination. of

The invention Consists of the improvements hereinafter.' described anti {ineiijv claimeti.

As manufactured the huh las secured thereto an outwardly curved spring arm the free end of which spring' arm is provided with a brush 'which lies in a plane substantially parallel to plane paasn ing through the dat part 17 of the hub the brush being out of alignment with the hule. The huh is notched as at 28 for engagement pin 14 upon the cam shaft 13 whereby the huh .is interlocked with respect to said shaft so as to he rotative therewith but is held against slipping therearound. The tubular hub being split may he readily fitted to cam shafts of slightly different diai'neters and the flexible arm likewise accommodates itself readily to timer easings of different diameters.

By reason of the flexible arm positioned as above described the brush positively and uniformly engages a contact-piece thus eri-- suring an equaldistribution of sparks to the engine cylinders so that the engine may he not only easily started but operate more elliciently. v Should a timer case have a Worn or pitted Contact surface a brush of the present invention, by reason of its uniform oontact, Will in ltime Wear such surface smooth. Replacement of brush arme and brushes by reason of the detachable 'features before de curing said arm to scribed adds to the commercial value of the article.

It Will'neW he apparent that I have de vised a novel and useful construction which embodies the features oi." advantage enumerated as desirable .in the statement of the invention and the above description and while l have in the present instance shown and described the preferred embodiment thereof which has heen found in practice to give satisfactory and reliable results, it is to he understood that the same is susceptible of niodilieation in various particulars Without departingv from the spirit or scope of the invention or sacrificing any of its advanw tages.

What I claiin is:

A timer brush comprising; a sleeve, a. spring arm mounted upon and extended from said sleeve, means for detaohably sesaid sleeve including a headed stud upon the sleeve and an aperture and slitin the arm, and restraining; means also extended from thesleeve for freely engaging said arm to limit the radial play thereof and to prevent substantial transverse movement of said arm.

imony whereof, .l have hereunto signed my name.
